CPC H04W 76/27 (2018.02) | 3 Claims |
1. A mobile communication system comprising:
a base station device; and
a terminal device, wherein the terminal device performs a radio communication with the base station device,
wherein the base station device transmits a control signal for causing a transition from a first state to a second state to the terminal device, the first state being formed when a radio connection of the radio communication is established, and the second state being formed at a time of waiting for the radio connection while storing information used to communicate with the base station device,
wherein the terminal device performs uplink transmission to the base station device using connection parameter information of the uplink transmission to the base station device in the first state in the second state to which the first state has transitioned in a case in which the control signal has been received,
wherein the base station device performs uplink reception from the terminal device that is in the second state to which the first state has transitioned, using connection parameter information of the uplink reception from the terminal device in the first state,
wherein the connection parameter information includes at least one of transmission timing information, physical resource information, or modulation and coding scheme information, and
wherein the transmission timing information includes a slot period or an offset value from a downlink frame, the physical resource information includes symbol positions or frequency positions of transmission resources, and the modulation and coding scheme information includes a channel quality indicator (CQI).
